Terahertz spectroscopy has emerged as a versatile approach for the detection and characterisation of gas-phase species by probing rotational and low-frequency vibrational transitions. In practice, two ...

Rotational spectroscopy exploits the absorption or emission of electromagnetic radiation by molecules as they undergo transitions between quantised rotational energy levels. When applied to molecular ...

Muon spin rotation (µSR) spectroscopy is a powerful technique that helps to study the behavior of materials at the atomic level. It involves using muons—subatomic particles similar to protons but with ...

Using muon spin rotation spectroscopy, researchers from Japan and Canada have successfully captured the rapid conversion of an imidoyl radical into a quinoxalinyl radical occurring within nanoseconds.
